hi,
i have the creative z2300 speakerset in my cabinet. I also had this model in my first cabinet, and mounted it like this

with the base pumping out like this

This worked fine and very controlled
With my new slim cabinet i have to mounth the sub on its side like this

So the woofer pumps to the right, even with the woofer volume at it lowest its still a lot.
What can i do to reduce the resonation?
I was thinking, maybe put a mfd shelf above the woofer with isolation?
